Hi, I am a beginner to android SDK and have almost no idea of using it. But I have to do it in any case. What I want is to select a .wav or .mp3 file stored on my android 2.2 phone. I want to read the samples of the audio file like 16 bit or 8 bit sample (whichever possible). Then I need to modify it and save the modified file back with some other name. Please guide me that how can I get started by reading a .wav or .mp3 and reading its samples. P.S.: I am a beginner. So, don't try to be over smart Thank you.
